SCIaimS.

The invention relates to new and useful improvements in a machine for applying friction covers to containers.

An object of the invention is to provide a machine wherein the container after it is filled has a cover applied thereto, which cover is firmly forced onto the friction seat therefor, while the container is moving in a straight line.

A fln'ther object of the invention is to provide a machine of the above type wherein the support for the container travels with-the container during the forcing of the cover onto the friction seat.

A further object of the invention is to provide a machine of the above type wherein the cover is forced onto the friction seat of the container by means of a traveling head which moves bodily in a circular path and is maintained during its bodilytravel in a vertical position with theface thereof which engages the cover horizontal.

A further object of the invention is to provide a machine of the above type with means for marking a cover and forplacing the same on a container when there is a container to be closed.

A further object of the invention is to provide a machine of theabove type wherein the filled containers are'fed to the machine at random and are spaced and delivered to the clbsing mechanism in timing with the movement of the closing mechanism.

These and other objects will in part be obviousandwilllnpartbehereinaftermorefully disclosed. I

The container as .head moves onto a supporting so as to travel with the tainer does not stop T but is closed while it is traveling.

After the cover has been forcibly seated in the container, it is removed from the traveling support and delivered from the machine while the traveling support moves rearwardly and is positioned to receive the next container.

Referring more in detail closing machine includes a main frame 1 whichisshown as mounted in part on wheels 2, 2 and in part on a standard 3 which provides a means whereby the machine may be readily moved-about the plant. Mounted on the main frameyl is a motor 4 which operates the entire machine; The

containers are received onto a disc 5 at random.

The containers are indicated at C. This disc of the arrow through suitable driving connections with the motor .discharges the containers against a guide rail 6 and this guide rail together with the movement of the disc 5 places the containers on a rotating support 7. Associated with this rotating support '7 are timing fingers 8. e

The timing mechanism forms no part of the present invention per se, .but is shown, described and claimed in the application of Mathew M. ,Sedwick, Serial No. 414,431; filed of even date herewith. These timing at a time and space the containers and deliver the same to a traveling conveyor 9. The traveling conveyor 9 is provided with spaced lugs 10 which receive the containers delivered thereto by the timing fingers.

The containers are moved by the conveyor 9 it passes beneath this closing table which is timed fingers select one container closing head. The conto the drawings, the

this arm 17 operates through a suitable clutch m 18 so that when a container v the arm and throws into action the cover feeding for supplying a cover for the container,ifthereisnocontainerthearm, then the cover feed is inactive. This cover feed which includes means whereby the stack holder may be readily adiusted'for covers of different sizes forms no part of the present invention per se but is shown, described and claimed in the application of George Flook, Serial No. 414,414, filed. body of even date herewith.

The marker for marking the covers includes a traveling marking head which remains in a vertical position during its entire 'movementand the marking head can, therefore, move down into a recess in a cover andimpress an identifying markinthebottomwalloftherecess. Oneofthe common forms of friction closed containers includes a container'having a top portion provided with a friction seat and the cover has a central.

depression forming a friction plug which is forced onto said friction seat. This type of container is so well known in the art that further description thereof is not thoughtnecessary.

The marker is so' constructed and operated as to impress an identif mark in the bottom wall of this depression forming the friction plug. as has already been noted. This marker forms no part of the present invention per se, but is shown, described and claimed in the application of Mathew M. Sedwick, Serial No. 414,430, filed of even date herewith.

The containers with the covers placed lightly thereon are delivered beneath a closing head 19. The clodng head 19 is mounted in a cross head 20. Said crow head is inthe form of a sleeve having laterally projecting portions 21. and 22. The closing head 19 is carriedby a stem 23'which is mountedin thissleeve 20andis-flrmly1ocked in adjusted positions therein. Said stem has the upper portion thereof threaded at 24 and the sleeve isthreaded to receive this threaded portion ingportions21and22respective1y."rhesleeveis 31whichareattachedtothe'cranksbymeansof bolts32.

Thus it 7 head can movevdown onto the cover when loosely applied to a traveling container and'force formed in a support or table 45. This support or a table 45 is mounted on i-ouors 48,48 and is adaptioo' ed to travel back and forth in a horizontal plane beneath the clomng head 19. The container 0 is shown with the cover 0 loosely applied thereto.

In the dotted line position 0 it is moved onto the support or table 45 and is shown in full line position C beneath the closing head. The closing head is pressing the'cover onto the friction seat andthe support or table is moving with the container so that when the head is'engaging thecover and forcing it onto the seat, the container and supporting table therefor are both moving. This prevents any possible tilting or'cramping of 'thepartsandenablesthecovertobeforced directiy downonto its seat. The container indicated at the positionC'inFig.4hasthecover flrinlyseatedthereonandtheheadisaboutto ,move away from the cover. The table is still moving in aforward direction. The container is moved off from the table onto the stationary supporting member therefor to the position shown at 1 C and then into the position shown at C and iinally delivered from the machine. The table is moved backand forth by means of a lever 46a. Said lever is pivoted at 47 and is connected by means'ofalink48toalug49dependingfrou nthe table. A spring 50 the lever 464. an

A roller 55 carried by the lever engages member 52. As the projecting cam portion 54 comes into engagement with the roller, it will move the upper end of the lever to theright, as viewed in Fig. 4, and this podtively moves the table in the direction of the arrow. This projecting cam portion 54 is so shaped and timed as to move the container at substantially the same speed as'the traveling head 19 at the time when the cover is being forced onto the friction seat on the container.

The shaft 53 is mounted in suitable v in the frame 1 and carriesa bevelgear 56 at; its inner end. bevel gear 56 meshes with a i bevel gear 5'iofiaverticalshaft58. 'l'hevertical shaft 58 carries a-bevel'gear 59 at its upper end which-meshes with a bevel gear 60 on'the shaft 35.. The shaft 35, therefore, through the shaft58impartsrotationtotheshaft53.

A sprocket chain 61a running over this sprocket wheel engages a sprocket wheel Sit) on the shaft 61c. The shaft 610 carries a sprocket wheel 62. The conveyor 9 runs over sprocket wheels 62, 63 and 64. The shaft 35 carries a sprocket wheel 65 and a sprocket chain 66 rimning over this sprocket wheel- 65 engages a sprocket wheel on the actuating shaft which imparts motion to the marker, cover feed and the the cover feeding turret.

The clutch controlled by the arm 15 is carried by this actuating shaft, and it is through the controlled clutch that the cover feed and marker are operated.

From the above it will be apparent that a machine has been provided wherein filled containers may be received at random, the covers applied thereto and said containers and assembled covers fed to a closing mechanism in spaced relation and in timing with the operation of the closing mechanism. The container is moved onto a table and as the head engages the cover for pressing mechanism in a straight path of travel so that there is little or no spill incident to the movement of the container bene th the closing head,

and furth more, the move J nt of the container in a vrigh line with the traveling head moving in a plane containing said right line movement of the container brings about a very easy and perfect seating of they cover in the container.

It will be understood that other types of friction closures may be closed on the machine embodying the improvements without departing from the spirit of the invention. It will also be understood that various changes in the details of construction and the arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claims.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is:- f
